Excluded Activity Types still showing

I'm trying to share a vCard using UIActivityViewController and I don't want to show apps that do not support it. Although excluding twitter and Facebook posts work when I use the share extensions provided by default, it fails to exclude apps like snapchat

Code Block 
UIActivity.ActivityType("com.toyopagroup.picaboo.share")

when it's not provided by apple.

Code Block 
            let activityVc = UIActivityViewController(activityItems: [fileLocation], applicationActivities: nil)
            activityVc.excludedActivityTypes = [
                UIActivity.ActivityType.print,
                UIActivity.ActivityType.copyToPasteboard,
                UIActivity.ActivityType.postToTwitter,
                UIActivity.ActivityType.postToFacebook,
                UIActivity.ActivityType("com.toyopagroup.picaboo.share") // still shows snapchat
            ]

Please Help
